The present invention provides devices and methods for attachment of an
implanted device, such as an artificial stoma device, a gastrointestinal
sleeve device or an attachment cuff, within a patient's digestive tract
for treatment of obesity. Special surgical fasteners provide a lasting
and durable attachment to the gastrointestinal tissue without causing
excessive pressure that could result in tissue erosion and detachment of
the implanted device. Fastener delivery devices that facilitate peroral
placement and deployment of fasteners and secondary devices are also
provided. Also described are implantable devices and attachment means
that avoid causing excessive pressure within the tissue by having
compliance that is compatible with the gastrointestinal tissues where it
is attached.
